This meant that partiers could no longer distance themselves socially properly and that the pub was closed by police, reports Examiner Live.
The popular pub on Brook Hill in Thorpe Hesley closed immediately and staff called South Yorkshire police for help.
Bars reopened for the first time on Saturday July 4 – dubbed the Super Saturday – since the lockout was imposed in the UK on March 23. Strict rules are in place to guarantee social distancing.
At 11:12 pm last night, the Red Lion posted on its Facebook page: “Tonight, we had to ring 999 quick answer and close the pub with immediate effect when we were inundated with literally dozens of strangers in the cafe in full air in about 90 minutes.
“The police later told us that it was because they had closed a number of pubs in the area and that this had created a wave of people looking for an open place – they chose us!
“Before that, the garden was occupied by the locals but manageable.
“Once we realized what was going on and the situation was downright dangerous, we reacted immediately, but unfortunately, it caused a huge crowd of people with nowhere to go outside. “
The post also said staff at The Horse & Tiger – a pub just down the street – had been alerted and its doors were also closed.
The news comes when UK drinkers were having problems on Super Saturday.

Devon and Cornwall police reported receiving more than 1,000 calls, mainly due to drunkenness and anti-social behavior by drinkers. Dorset police recorded 525 incidents in 24 hours.
